Crytek announced The Climb would most likely be causing a record amount of vertigo exclusively on the Oculus Rift, and today, it’s released its first developer diary that shows what went into creating the title.

The developer diary invites viewers to meet the team who are working on The Climb, their inspiration to create their first prototype, and the moment-to-moment fear and excitement of clinging onto a cliff that’s positioned hundreds of meters above the earth without the luxury of a safety net.

The Climb is currently in development and is expected to be available around the Oculus Rift launch.
